Dolphins assistant offensive line coach quietly departs

Chris Mosley, an assistant offensive line coach for the Miami Dolphins, has left the team, the Sun Sentinel has learned.

Mosley's absence cannot directly be connected to the workplace issues that have engulfed the Dolphins since offensive tackle Jonathan Martin left the team last week.

His departure took place in early October, and his role has been filled by Marco Rivera, a coaching intern, for at least the past five weeks.

"Chris was on an extended leave dealing with a personal matter, and he and the organization mutually agreed to part ways," a team spokesman said.

But considering the source of the Dolphins' workplace environment scandal centers around the offensive line unit, and what took place inside those meetings, it is possible Mosley could become part of the NFL's independent investigation into Martin's allegations that some Dolphins players bullied him, and created a hostile work environment.

Earlier this week the Sun Sentinel reported that Dolphins coaches instructed team leader Richie Incognito to "toughen up" Martin this season, getting the 2012 second-round pick ready to handle his role as the Dolphins' starting left tackle.

Martin left the team after a prank his fellow offensive linemen played on him the day after he started his first game at right tackle in 2013.

Martin's attorney, David Cornwell, objected to those questioning Martin's toughness, and stressed that his client was a victim of constant harassment, which featured threats made to Martin and his family members.

"For the entire season-and-a-half that he was with the Dolphins, he attempted to befriend the same teammates who subjected him to the abuse with the hope that doing so would end the harassment."

Both Martin and Incognito were starters on the Dolphins offensive line, which had struggled all season, and presently leads the NFL with 35 sacks allowed. Martin was moved to right tackle because the Dolphins traded a conditional late-round pick to Baltimore to acquire veteran left tackle Bryan McKinnie.

Mosley, 35, was hired by Joe Philbin in 2012. Jim Turner was the lead offensive line coach, and Mosley worked under him.

Before joining Miami's staff Mosley served as the offensive line coach at Saint Anselm. Before that he spent two seasons with the Tampa Bay Buccaneers as a position coach.

His tenure in Tampa Bay concluded in 2010. During that season, Mosley was arrested on charges of driving under the influence.

A recent search of South Florida's police records indicate Mosley hasn't been arrested locally since that incident.
